"I think what we are doing is making sure that the sponsoring organisations truly are what they say they are in the United States; that if they say that they are bringing students over to educate them, that they intend to educate them, not put them to work, et cetera," she said.

Nuland said the US supports the recent initiative of opening community colleges in India on the pattern of those here.

Last week, education ministers of four Indian States - Punjab, Bihar, Madhya Pradesh, and Jammu and Kashmir, visited several US cities to have a first hand experience of the community colleges here.

"Well, obviously, we support this initiative. We have been working with the Indian side to flesh out the initiative that was agreed between the President and the prime minister through our Education Bureau here. And obviously, we are responsible for the visa issuance for the various folks studying in the United States," Nuland said.
